My 11 day old is now solely formula fed after some combi feeding. She hasn’t been for a poo in almost two days and the last three she did two days ago were hard pebbles which she struggled to pass. Midwife yesterday said to be expected when getting used to formula and not to worry, it could take a couple of weeks. I said if she doesn’t go at all is there a time limit I should seek help and again she said a couple of weeks; this seems excessive to me! Has anyone else got any experience with this? Will it resolve itself??
